Whilst futzing about the Shenandoah Valley today, I noticed that I had an EGT reading abnormally low compared to the others. I have a GRT EIS 4000. It's a simple design but I gotta admit I'm in love with the thing.
Won't lie - I'm a better pilot than I am systems guy and I am still learning this airplane. I don't recall seeing something like this before, but I might also be a moron and I'm totally mis-interpreting what I'm seeing.
The first picture shows my EGTs as I was be-bopping along:

The second picture shows the CHTs:

The engine was performing just fine - no issues, everything was smooth. And since the CHTs were where I expected them to be, I'm wondering if the odd-man-out in the EGT picture is a bad sensor?
If so, I'm guessing troubleshooting would involve moving/swapping the sensor with another one and then seeing if the problem followed the sensor or remained in the same place.
If it follows the sensor, then the sensor is bad. If it doesn't.....
what do I do?
(still trying to figure out how to embed the images. following directions but every time I use the Insert Image it hides the link)
